This invention relates to the field of cases designed to contain cosmetic products or beauty products, typically makeup powders.
In general, cases typically comprise:
a hollow cover in which an inside mirror is fitted;
a hollow bottom fitted with a grid or intermediate support for at least one receptacle that will contain the said cosmetic product;
a hinge, forming the connection device between the said cover and the said bottom such that the said cover can rotate and open the said case;
a closing device or any means of locking and unlocking the said cover to or from the said bottom, to open and close the said case, a typical closing device being a push-button.
Many embodiments of makeup cases are known, that may concern one or several components of the case.
Thus, the following is a list of some patents deposited by the applicant:
patent FR 2 661 080 that describes a compact makeup case and closing device;
patent FR 2 701 365 that describes a transformable makeup case;
patent FR 2 725 958 that relates to a case with a flush closing device with assisted opening;
patent FR 2 737 192 that describes a case with a tilting cover fitted with a hinge with flexible tabs;
patent FR 2 755 352 that describes a case with assisted opening;
patent FR 2 755 353 that describes a case with an unlocking and preliminary opening push-button;
patent FR 2 756 155 that describes a makeup case of the type comprising a bottom, an intermediate plate and a cover on which an inside mirror is fitted.
After cosmetic products have been packaged, usually in the form of solid products or possibly very high viscosity non-fluid pastes, an applicator for the said cosmetic products may be added to the case, typically a powder puff in the most frequent case in which the said cosmetic product is a makeup powder, the shape of the powder puff being the same general shape as the case and being placed inside the case between the said mirror and the said receptacle filled with the said cosmetic product. The said powder puff is usually made of a soft and fibrous material, so that a little powder can be taken out of the receptacle and then applied on the face.
Cosmetic products designed to be packaged in cases are developing towards more and more complex formulations designed either to fulfill new functions, or to more efficiently fulfill known functions.
A problem arises in the case of formulations comprising a volatile product, since standard cases are not airtight. This problem is solved by the use of sealed receptacles inside the cases.
However, these cases with sealed receptacles are not easy to use to the extent that there are two covers, each with its hinge and its diametrically opposite closing device. Consequently, for reasons of compactness, the hinge and the closing device of the receptacle are oriented at 90° from the hinge and the closing device of the case. Thus, a person opening the case normally holds the case with one hand while the other hand lifts the case cover, and then finds a receptacle in which the closing device will be at his right or left so that he will need to change hands, for example if the free hand that opened the cover is the right hand whereas the closing device is at the left—or vice versa.
The invention is intended to solve this problem and to make a case with an airtight receptacle that can be adapted to any left handed or right handed person.
According to the invention, the case comprises a cover and a bottom fixed and hinged by means of a first hinge, a first closing device for the said cover, and contains a sealed receptacle comprising a bottom and side wall fitted with an airtight cover fitted with a second hinge and a second closing device, and is characterized in that:
a) the said receptacle is a receptacle that can be click fitted/separated in the said case by clipping means consisting of cooperation between male parts (typically ribs) and female parts (typically grooves), the ribs being formed on the wall of the said receptacle and the grooves being formed on the said bottom of the said case;
b) the said receptacle can be clipped such that the said second closing device can be in two different orientations from the said first closing device; such that the user of the said case can orient the said receptacle himself or herself with respect to the said case depending on whether he or she is right handed or left handed, to make it easier to open the said receptacle later.
FIGS. 1 and 2 are views of cases (1) according to the invention, along a section through a vertical plane.
FIGS. 3 and 4 are diagrammatic views of the cases according to the invention, along a section through a horizontal plane.
FIG. 5 is a side view of a case according to the invention.
In the case (1) according to the invention, the bottom (3) of the case (1) has an orifice or opening (33) enabling manual contact with the bottom (7, 70) of the said receptacle (4) so as to exert the manual pressure necessary to facilitate separation of the said receptacle (4) as shown in FIGS. 1 and 2.
As illustrated in FIGS. 3 a, 3 b and 4 a, 4 b, the said receptacle (4) may be placed in two different orientations with respect to the said case (1), such that the B axis (52) formed by the said second hinge (51) and the said second closing device (50) of the said receptacle (4) forms a right angle with the axis A (22) formed by the said first hinge (21) and the said first closing device (20) of the said case (1) and in that the said second closing device (50) can be at 90° to the right or left of the said first closing device (20).
According to the invention, the bottom (3) of the case has two side clipping ribs (31) at 90° from the said A axis, a right rib and a left rib, and there is a hollowed out part (61) in the wall of the said receptacle adjacent to the said second hinge in which the said clipping rib fits, and there is a groove (60) adjacent to the said second closing device, that will cooperate with the said side clipping rib (31), such that when the said receptacle (4) is opened, the vertical force typically exerted on the second closing device (50) will not pull the said receptacle (4) outside the said case (1). If the bottom (3) of the case is formed by a plane bottom and a side wall, the two side clipping ribs (31) are fixed to the said side wall.
This embodiment is shown in FIG. 1, the right part of the figure showing how a rib (31) fits into a groove (60) formed on the side wall (6) of the receptacle adjacent to the closing device and underneath the closing device (50), whereas the left part of the figure shows a hollowed out part (61) under the hinge (51) that prevents the receptacle from engaging with the rib (31) facing the said hollowed out part. This facilitates intentional separation of the receptacle, and prevents accidental separation when the receptacle cover is opened.
Cooperation between the said grooves (60) and ribs (31) may be chosen such that the extraction force to extract the said receptacle (4) or to release the receptacle from the case in order to modify its orientation, is at least twice as high as the vertical force normally exerted to open the said sealed cover (5), which is usually between 3 and 10 N, and is less than the maximum force that the average user is prepared to apply (typically 50 N) in this type of situation, as a function of the number and depth of pairs of ribs and grooves.
Typically, the said bottom of the case is fitted with 4 clipping ribs (31) at 90° from each other, two being along the A axis, the said wall (6) of the said receptacle comprising two opposite grooves (60), each being at 90° from the said B axis, as can be seen on FIGS. 1 and 2.
According to one embodiment of the invention, the said bottom (3) may comprise a grid (30) clipped in the said bottom, the said grid forming the support of the said receptacle and on which the said male clipping parts, typically ribs (31), are fitted as illustrated in FIGS. 1 and 2.
According to another embodiment of the invention, the bottom (7) of the said receptacle comprises a shoulder with a lower part (70) penetrating at least partially into the said orifice or the said opening (33) in order to facilitate manual separation of the said receptacle.
This lower part (70) may have a section that cooperates with the section of the said orifice or the said opening, as illustrated in FIGS. 1 and 2.
As illustrated in FIG. 5, the side of the bottom (3) of the case may be provided with two recessed parts (32) oriented at 90° from the A axis in order to facilitate manual gripping of the said second closing device.
The invention is not limited to an arbitrary shape of the case. Therefore, this case may be of any shape whatsoever, typically round, square, rectangular, oval or oblong.
Cases were made using the elements in FIGS. 1 and 2.
The shape of a section through the horizontal plane of these cases is round, corresponding to FIGS. 3 a and 3 b, and the shape of a section through the vertical plane is oval, as shown in FIGS. 1 and 2. The bottom (3) of the case is fitted with a grid (30) irreversibly clipped into the said bottom (3), the grid being fitted with 4 ribs (31) at 90° from each other, and acting as a support to the said receptacle.
The side of the bottom (3) of the case (1) has two recessed parts (32) along the B axis of the receptacle as shown in FIG. 5.
The diameter of the receptacle (5) is 50.8 mm and its height is 7 mm.
It has a rib (60) under the closing device, two side ribs on each side at 90°, and a hollowed out part (61) under the closing device.
The bottom (7) of the receptacle has a lower part (70) adapted to the shape of the 20 mm diameter opening (33) located in the lower part of the said bottom (3).
Users (particularly left-handed users) evaluated the ease of opening the receptacle using cases according to the invention and the ease of reorienting the receptacle if required, in comparative tests carried out on standard cases according to the state of the art and on cases according to the invention, and recognized that this ease of use was advantageous.
Advantages of the Invention
The invention solves a problem for left-handed persons that has not been solved in the past, in a very practical and sensible manner at no extra cost, since cases with receptacles are usually made to be opened by right-handed persons.
